SMBus for LCD Panel Applications
The list of ID values for vendors is shown in Table 3.
Thermal Shutdown
The MAX17061 includes a thermal-protection circuit.
When the local IC temperature exceeds +160°C (typ),
the controller and current sources shut down and do
not restart until the die temperature drops by 15°C.
When thermal shutdown occurs, Bit 1 of fault/status
register is set to 1.

Design Procedure
All MAX17061 designs should be prototyped and test-
ed prior to production. Table 4 provides a list of power
components for the typical applications circuit. Table 5
lists component suppliers.
External component value choice is primarily dictated
by the output voltage and the maximum load current,
as well as maximum and minimum input voltages.
Begin by selecting an inductor value. Once L is known,
choose the diode and capacitors.

Step-Up Converter Current Calculation
At light loads, the MAX17061 automatically skips pulses
to improve efficiency and prevent overcharging the output
capacitor. The output current for the converter SKIP oper-
ation can be calculated by the following equation:
V IN ON ( MIN ) 2 × f OSC
× T

where I O(SKIP) is the output current in SKIP mode, V IN
is the input voltage, T ON(MIN) is the minimum on-time,
and V DIODE is the forward voltage of rectifier diode D.
